一个用ＪＡＶＡ写的序列化的例子 大家看看 不大 但能说明问题

import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.io.FileInputStream;
import java.io.ObjectInputStream;
// 标记模式
//深复制模式
class student implements Serializable{
	String name="zhangsan";
	int age=20;
	teacher cc=new teacher();
	
}
class teacher implements Serializable{
	String name="lifeng";
	int age=34;
}

class test{
	public static void main (String[] args) {
	student ss=new student();
	try {
		FileOutputStream fos=new FileOutputStream("aa.obj");
		ObjectOutputStream oos=new ObjectOutputStream(fos);
		oos.writeObject(ss);
		//-------------------------
	FileInputStream fis=new FileInputStream("aa.obj");
	ObjectInputStream ois=new ObjectInputStream(fis);
	Object object=ois.readObject();
	student aa=(student)object;
	System.out.println (aa.name);
	System.out.println (aa==ss);
	System.out.println (aa.cc==ss.cc);
		
		 
		
		
    
}
catch (Exception ex) {
	ex.printStackTrace();
}	
		
}
}
